[GUIDE] [HOW TO] Rooting your ZTE Blade II

32 posts in this topic

Myself or MoDaCo take no responsibility if something goes wrong, do this at your own risk! The warranty on your phone will probably be lost if you do this! However, if there would be any problems, we will try to help you as best as possible.

1. General Information

2. The Guide step-by-step

3. Trouble-shooting / F.A.Q

4. Credits

1. General Information:

This guide is for the Blade II mobile phone, and will not work for any other device! (unless it's confirmed). The specifications about the phone can be seen here: (http://pdadb.net...&c=zte_blade_ii).

Before you start make sure you have access to an computer, that you have the drivers for your phone installed on the computer, that you have added the Superuser zip-file on the SD-card and that you ticked the USB-debugging on your phone. (You can find it under Settings/Applications/Development).

(Make sure that the recovery file is called "recovery.img" and nothing else).

2:9. Then type in the command prompt window: "fastboot reboot"

(The mobile phone should now start up as normal).

2:10. Now switch off your phone, and remove the battery for a little while, and insert it again. Then start the phone again by holding the volume-down key - and the start button at the same time. (It could be that it flashes and the green man comes up again, but it's nothing to worry about, just hold down the buttons all the time).

2:11. You should now have got into recovery. (Use the volume-keys to scroll through the options, and the home button to select).

2:12. You should now select: "install zip from SD-card", push it, scroll until you find the "Superuser-3.2-RC2-arm signed.zip" file, select it and then press "Yes". (You might have to scroll through a few "No", until you reach "Yes").

2:13. Congratulations you should now have rooted your Blade II phone. (Now just start the phone up and see in the menu if Superuser application is installed).

3. Trouble-shooting / F.A.Q

3.1: Q: I'm stuck at "< waiting for device >" in the command prompt window after running: "fastboot flash recovery recovery.img", what is the problem and what to do?

3:1. A: Unplug the USB-cable and remove the battery for a short while, then start it up again and make sure you have USB-debugging checked. The problem is most likely that your computer haven't installed all the drivers correctly. To trouble-shoot this you'll have to download and install a program called "PdaNet". Follow the instructions from the installation-process, and proceed with step 7 in the guide. Get PdaNet @ http://junefabrics.c...droid/index.php

Hope everything goes well now. And please write a comment how it went later. Thanks for me! :)

*** Main post is not finished, it might be updated with more trouble-shootings / F.A.Q or more Information, but the guide rooting procedure will stay intact. If there is anything you wish to be added to this guide, or something needs to be changed, feel free to inform me about it and i'll updated the post. ***

Well, i don't know where else to put it.. The fact that it's an ZTE manufacturer phone, tells me it should be in this category. And that the phone device name is Blade II indicates it should be in this section.

I havn't seen any section for the Blade II version, but i could be wrong. If this thread is in the wrong section, can an moderator please move it? Sorry for any inconveniences, it's a bit misleading.

So i was having problems like many others that "waiting for device" message and nothing happened .

I fixed this issue and i like to inform ,help others whos still fight with this problem.

This message is have to do with the zte drivers in windows , so everithing is just cause drivers !!!

So i'm using Win 7 64bit and now i tested at my office also on Win 7 32bit (both ultimate) and it worked.

What you need to download what fiskbulle mentioned abowe , so

1. i extracted the 'adb_fastboot_and_other_tools.zip' to c:\ so we have C:\Android\

2. I append the C:\Android\ in the ENVIROMENT VARIABLES at PATH clicked EDIT then after the paths append ;C:\Android\ (copyed here the recovery.img and , Superuser-3.2-RC2-arm-signed.zip to the phone SD)

3. On my blade2 checked the USB DEBUGGING settings then connected to computer

4. At this point i opened the DEVICE MANAGER to see allthetime what happening with the phone drivers

5. I installed the usb drivers mentioned abowe. (and i was looking at device man to ensure that there is no error in drivers)

6. At this point i opened a COMMAND PROMPT from c:\android\ then i checked my phone with 'ADB DEVICES' command ,... list of devices attached P735T was written

7. now i type 'ADB REBOOT BOOTLOADER' then the phone after 5-7 sec reboots to the Green android screen and stuck there :)

8. At this point my device manager lost ZTE HANDSET MODEM, ZTE COMPOSITE ADB INTERFACE devices and found a new one ,ANDROID with driver error !!! Important to set the DEVICE ISTALLATION SETTING in windows to use INSTALL DRIVERS FROM WINDOWS UPDATE IF NOT FOUND ON MY COMPUTER

9. i choosed UPDATE DRIVER from DEVICE MANAGER , and updating from the internet , after a while it found a driver and installed , and i got finally a working device named ZTE BOOTLOADER INTERFACE or whatever it was :)

10. At this point i checked with ADB DEVICES my phone , but dont worry its not seeing like before , but its communicating anyway !

11. so I typed the 'FASTBOOT FLASH RECOVERY RECOVERY.IMG' then it starts the process ,after 3-4 sec its finished.

12. now typed 'FASTBOOT REBOOT'

13. Phone restarts normally , then powered off , battery taken out for 10 sec , power button pressed for a while.

14. Restarted the phone by holding the Power button and Volume Down buttons until i entered in clockworkmode recovery ! :)

15. Then i used INSTALL ZIP FROM SD CARD and choosed the Superuser-3.2-RC2-arm-signed.zip , flased and rebooted after.

16 Phone restart normally , i used ROT CHECK to check if my device is rooted , you found on the market.

There is important notice from "jenck": when rebooted to bootloader, the device really change from "zte blade" to "android interface device". I have windows vista and there was no "update online" option for the driver. So I googled "android device driver" and find it. It seems to be some generic android usb driver. Other stuff works as described by fiskbulle.

I bought ZTE blade 2, already rooted and my big fault I didnt make a recovery and I make a factory reset... So I finally discovered that there is no recovery img or cyanogenmod for this phone, even on ZTE site. So I cant use it until they release recovery.zip or cyanogen will support zte blade 2. Or anybody have some idea what I can do except waiting for new firmware? Thank You a Lot.

Thank you!

i'll test it out and let know if it works, I fear it wont because I bought mine in Belgium :/

EDIT: did not work as I suspected...

it said: status 7 aborted instalation and something with the getprop product device and the getprop build product. (because its a diffrent version i guess?)

Can you please tell where on the website you found this ROM? maybe I can find one for the Belgian edition.

Open the archive and extract the file updater-script (META-INF/com/google/android /). Edit it with Notepad and remove the first three lines. And and save it. Put it back in archive replacing the old one. Take the zip file and put it on SD. Use CWM and install the modified zip file from SD card. This time there will be error. Until the end an error will appear. Ignore it and boot the phone.

After some time the phone will boot with the new operating system.This process will remove CWM and FTM mode be back again. Though you can reinstall the CWM.

Unfortunately there is no working moded ROM available for ZTE blade so far. So far no problem with new operating system and quit alot of mess is removed compared to factory one.

For me After installing the Stock ROM with this method, not a single CWM works, it just boots in FTM mode. So no rooting on my phone for now.

Thanks for typing this up. If only I found your post before the Swedish one so I wouldn't had to decrypt his instructions.

It works perfectly for me, except I'm having the same CWM issues you mention. Have you found a solution or a workaround that enable you to root your phone? I'd greatly appreciate if you could share this.

Instead of executing "fastboot reboot", simply disconnect the USB cable and remove the battery for a while. After having reinserted the battery, power it on in the typical recovery fashion (holding down the "volume down" button and pushing the power button until the device begin its boot process, do not release the "volume down" button before you have entered CWM recovery) and you should enter CWM recovery.

EDIT: Apparently, you'll only be able to access CWM recovery on this sole instance. In any further attempts you would simply land at FTM ("volume down") or Android recovery ("volume up" or "adb reboot recovery"). If you want to enter CWM recovery again, you're going to have to redo the flashing process and remove the battery, as explained earlier in this post. Such is at least the case for me.

BOW DOWN TO THE SAVIOUR :D :D

This is a nice trick.it worked and I just need one boot in CMW to install super user for root access and I got it. Thank man. I will quote your solution in other threads. BTW which version CMW you tried. I heard v 6.x.x.x should also work on Blade2.

Also it would be nice idea if the fix posts should be linked in the main post of this tread.

For a newbie some explainations, on how to effectively do the root, like where to put the files, remain in the comp. or transfer on SD card, the phone should be all the time conected by usb cable, i am really confused, after applying root method need to install a diferent rom, the stock one is stil working?

If someone will find time and patience to answer, many thanks.

Later Edit

I done using info provided by Jenck in post 4 (thank's) step by step. About the memory i use now link2sd with a ext2 partition on my sd card, work fine even with widgets, Stil searching for a custom rom, seems there are not any available for this phone.
